New Owner

Well folks, I joined the Audi family. I purchased an '86 5000CS on
Wednesday. It's in great shape. 96,000 miles, and unfortuntly, an
automatic.
Two questions:
The guy I bought it from had the trans-axle fluid replaced before
I bought it at the local dealership. I drove it less than 2 blocks from
the dealership and the tranny started whining. More noticable when
deceleration. Did I just not notice it before and it is been there all
along or is it possible they screwed up??
Second, need to get a Bentley (I been on this list for a while).
Anyone know the cheapest place to find one? Anyone got one for sale?
Talk to you later
